IMPROVEMENT IN CULTlVATORS.

Specification forming part of Letters Patent No. 36,998, dated November25, 1862.

To all whom it may concern:

Be it known that 1,0. B. I NGERsoLL, of Morris, in the county of Grundyand State of Illinois, have invented a new and useful Improvement inGultivators; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing's, and to the letters and ligures marked thereon,whiclr form a part of this specication.

In the aforesaid drawings, Figure l represents a plan or top View of myimproved cultivator, and Fig. 2 a side view of the same.

Similar letters in the different ngures in the drawings denotecorresponding parts of my invention.

Myinvention consists in theim proved method ot' applying the draft tothat class of cultivators which are made very high, soas to cultivateboth sides of the saine row at once -without breakingv down the corn,cotton, &c. In this class of cultivators the draft as commonly appliedcomes entirely upon the front of the upper part, and has a tendency t0tip the cultivator down toward the front, thus making it very hard workfor the horses to draw it and for the operator to manage it, besidesdoing the work in an imperfect manner; but by my in vention thisdifculty is entirely obviated, the draft being transferred from the topof the cultivator to the center or below it, and thus the cnltivator isdrawn along steadily and evenly with great ease, both to the horses andoperator, and doing the work in a perfect and desirable manner.

To enable others` skilled in the art to construct and use my improvedcultivator, I will now proceeed to describe the same with particularity.

In the accompanying drawings, D, E, F, G, and H represent the frame andhandles of the cultivator, D being the tongue, and G being thestandards, to which the shares marked S are attached by the braces m.These standards G are strengthened and made 'firm by means of the bracesn.

A represents the horizontal whifietree, to which the harness traces areordinarily attached, and B represents two other vertical whiftletrees,arranged as shown in the drawings, the upper ends ot' which areconnected with the extremities of A by means of the hooks a c and thechains b. B is kept in position by means of the iron straps or supportsC, which are lirmly fixed to G by bolts.

d is the rod or chain to which the traces are fastened.

It is readily seen that by this arrangement the draft is transferred`from the point c in the tongue and carried down to the point e in G, andat the same time all the advantages of the double whiftietree or evenerA are retained. This pointe', at which the draft is applied, isadjustable, and is to be varied to suit the character of the soil, beingso chosen in each ease that the center of draft and the center of motionshall lie in the same plane and substantially coincide, thus obviatingthe tendency of theeultivator to tip down toward the front, as itmanifestly would do it' the draft were applied at the point c, andgreatly diminishing the power necessary to draw it. as well as the laborto control it.

Myinvention has no reference to that class of cnltivators which aresuspended upon wheels; but

What I do claim as my invention is- The combination and arrangement of'the draft-pole D, the double-tree A, the beams E, the cross-beam F, thestandards G, the supports G, and the whiffletrees B, when all areconstructed, arranged, and operating substantially as and for thepurposes/herein delineated and set forth.
